Serial No. 297,898.

My invention aims to provide improvements in buttons and particularly sheet metal buttons adapted to be attached to supporting means by tacks.

In the drawings which illustrate a preferred embodiment of my invention Figure 1 is a vertical section through a complete button installation with the tacks shown in elevation;

Fig. 2 is a view of the parts of the button assembly just prior to attachment of the parts to the carrying medium;

Fig. 3 shows in an illustrative manner the method of detaching the head of the tack for disassembling the installation; and

Fi 4 shows a modified form of button D head construction.

Referring to the embodiment of my invention illustrated by the drawings, I have shown a button which is particularly adapted to be secured to garments or other ma terial by means of a metallic fastening device, such as a tack.

The body portion of the button (with the exception of the head) is substantially the same as more fully shown and described in my co-pending application Patent 1,760,835, dated May 27, 1930. This particular button is made of two pieces as distinguished from the one illustrated and described in my copending application. Also,-the tack unitis of novel construction and will be more fully hereinafter described.

The button illustrated by Figs. 1, 2 and 3 has a body portion which includes the head formed of two pieces 1 and 2, a cupshaped shank 3 formed integral with the piece 2 0f the head and an anvil portion 4 formed integral with the shank 3. The double wall portion 1* at the bottom of the shank is turned inwardly to provide a restricted opening 5 into the chamber 5.

The piece 2 forming part of the button head is cup-shaped and has a peripheral outwardly flared wall 6 over which is crimped the peripheral edge portion 7 of the piece 1 to secure the piecesof the head in spaced relation. An aperture 8 is provided in the piece 1 to align with the open end of the 9 cup-shaped shank 3 so that asupporting medium 9.

tool may be engaged with the anvil portion 1 when the button 'is being attached to the carrying medium 9. .As the pieces of the button head are. spaced from each other I find it is desirable to support the piece 1 adjacent the aperture 8. Therefore I have provided as shown in Figs. 1 and 2, a wall portion 10 which engages the piece 2 to-aot as a support and prevent distortion of the piece 1.

The buttonis secured to its carrying medium 9, by means of a tack having a head 11 and a shank 12. If desirable a cap 13 may be secured to the head 11 of the tack to provide a neat finish.

In attaching the button to the carrying medium 9., I may use a hand tool or automatic machine (not shown) having a tack holding die and a die to fit into the aperture 8 in thebutton head at the mouth of the shankB. Therefore when the dies are forced toward each other the shank 12 of the tack will be forced through the carrying medium 7 into the chamber 5 where the pointed portion will be upset as shown in Fig. 2, to provide a curled portion 14.

'.This curled portionengages the internal wall 4* and holds the button-in place,

The tack as illustrated in Figs. 2 and 3 has an annular recess 15 at the junction between the head 11 and shank 12 to set the connecting portion away from the carrying Thus when it is desirable to remove a button I may placethe capped head of the tack against a cutter 16 (Fig. 3) whichwill cut through the cap 13 and head 11 to sever the head 11 from the shank 12 without injury to the carrying medium 9.

Referring now to the embodiment of' my invention illustrated by Fig. 1, I have shown a button which is the same as the one above described except that the wall 17 which supports the piece 1 of the button head extends downwardly into the mouth of the shank 3 and seats against the anvil 4: to support the piece 1.

While I have illustrated and described my invent-ion as to specific forms of the button and tack I do not wish to be limited thereto as the scope of my invention is best defined in the following claims.

I claim:

1. A two piece sheet metal button having a head formed from two pieces of metal secured together, a cup-shaped shank formed integral with one of the pieces of said head and fastener upsetting and retaining means formed integral with said shank for automatically upsetting and clenching a portion of afastening element forced into engagement therewith.

2. A two piece sheet metal button having a head formed from two pieces of metal secured together at their peripheries, a cupshaped shank formed integral with one of the pieces of said head and fastener upsetting and retaining means formed integral with said shank, said means comprising an anvil portion formed by pressing the bottom of the cup-shaped shank toward the open end or" the shank and inwardly turned means at the bottom end of the shank providing a restricted fastener receiving openmg.

3. A twopiece sheet metal button having a head formed from two pieces of metal secured together at their peripheries and having substantially parallel spaced portions forming the head of the button, means providing a central opening in the button head, and supporting means provided as an inte ral portion of one of the substantially parallel portions of said head adjacent to said opening to engage and support the other piece of said button head and prevent crushing of the head and a shank extending from said button head.

4. A button installation comprising, in combination, a button having a head, a shank and anvil means, a button carrying medium, and a tack having a head, a shank piercing the carrying medium and upset by the anvil means of the button to secure the button to the carrying'medium and means providing a recess at the junction of the head and shank of the tack whereby said head may be easily severed from the shank, by removing the material adjacent to the bottom of said recess.

In testimony whereof, I have signed my name to this specification.
